Wavelength comparison study For photocurrent and thickness in organic tandem solar cell with PF10TBT:PCBM by computational simulation

چکیده مقاله

In this work, we have been investigating an organic tandem solar cells composed of PF10TBT:PCBM by
using optical modeling and simulation method to investigate the correlation between thickness and photocurrent.
Possible thickness pairs of tandem cell are provided when front layer and back layer absorb
same amount of photons. In order to obtain the possible thickness pairs for different wavelengths, photocurrent
has been simulated as function of back and front layer thickness. Energy dissipation in term of
distance along cell and wavelengths were analyzed to interpret the optimal geometry of tandem cell. In
order to find the appropriate materials for maximum efficiency, energy dissipation as function of optical
constant (n) and wavelengths were simulated to derive the optimal condition.
